At the end of Summer, Puss discovers that his radiator antifreeze solution has dropped below the safe level. If the radiator contains 4 gallons of a 25% antifreeze solution, how many gallons of pure antifreeze must he add to bring it up to a desired 50% solution? how to solve this and please solution

The new capacity is 4+x=y

Where x is the pure anti-freeze,
y is the total capacity.

4+x=y
0.25(4)+x=0.5y

1+x=2+0.5x
x=2

He needs to add 2 gallons of pure anti-freeze.

No 2 gallons is the correct answer.

No, its 2

its 2.

The answer is 2

i do not think that the answer to this question is 4/3 the quoins asks
